[Is an act of human love the in vitro fertilization? A proposal ethical analysis].

Since 1978, when the first test tube baby, Louis Brown, was born, thousands of children have been born every year through in vitro fertilization. Many families keep attending fertility clinics in order to receive some treatment for their infertility problems and have a child. Children born in this way are worthy human beings. Their parents love them and devote themselves to their children admirably, showing real parental love. However, does this loving kindness justify, from an ethical point of view, any way of desiring and having a son or daughter? Is it really an act of human love to long for a child and satisfy this desire using artificial methods? Is it equally human and worthy to wish them choosing in vitro fertilization than to wish them through an intimate and loving relationship, in which the child emerges as a result of interpersonal donation? I answer these questions by analyzing the ethics proposal formulated by Rhonheimer and Carrasco de Paula. In short, only the intimate and loving sexual union between a man and a woman -as long as it is unconditional love- may be the dignity cause of the existence of a human being. And such union and unconditional requirement are absent in vitro fertilization.
